Looks like a decent addition to the game, though it's not a major breakthrough in terms of design. I like how your supports can sacrifice themselves to save you from a ring-out and some arena destruction gives a bit of oomph to your attacks etc, though I kinda hope the ring-out feature can be disabled in the pre-game options, otherwise I'm seeing a huge increase in people that play as Pain.

There's supposed to be over 40 stages. I hope they keep this limited to only a few of them or maybe the function to turn it off. With that being said I do like the idea and I did enjoy the Tournament arena in the DBZ games.
